REED-ORGAN.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed March 30, 1910. Serial N 0. 552,403.

To all whom it may concern:

Be itknown that I, OLIVER H. Run, a citizen of the United States, residing at Ivanhoe, in the county of Fannin and State of Texas, have invented new and useful Improvements in Reed-Organs, of which the following is a specification.

My invention relates to a removable attachment for a reed organ or harmonium, to

be placed upon the wind chest behind either the treble or bass end of the keyboard, or at both ends, whereby the range of the instrument may be increased to either a higher or lower tone or both, so that an instrument with a five octave keyboard may have a range of six or seven octaves without extending the keyboard or making extensive changes in the construction of the instrument.

The attachment constituting my invention consists essentially of a set of reeds and its appropriate valves, mutes and swells, mounted in a suitable frame adapted to be placed over an air hole bored in the sounding board or top board of the wind chest, and back of the key and stop banks, and removably secured to the instrument by any suitable means. Proper connection is made with either a permanent stop or a special stop mounted in holes bored in the stop frame, so that the attachment may be drawn into action at the wish of the performer, the construction being such that all crossing of key levers is avoided, and all of the keys, when in use, are given the same pressure as the regular keys of the instrument to which it is attached.

My object is to obtain, in devices of this class, a simplicity of construction and manipulation which will enable the attachment to be adjusted to any instrument of the sort with a minimum of change of the permanent parts of the instrument, and to be removed at will, leaving the instrument in practically unmutilated condition.

In the accompanying drawing, Figure 1 is a view, partly in section, looking from the rear of the instrument, showing my attachment and its application, the figure being upon a reduced scale. Fig. 2 is a view in transverse section upon a larger scale.

Similar letters of reference indicate similar parts in the respective figures.

Referring to Fig. 2, A represents a depressed organ key, and A an organ key in normal position.

B is the tracker pin or plunger through the medium of which the regular outfit of reeds is caused to sound.

C is one of a series of coupler but-tons interposed between the organ keys and the series of levers D and D of my improved attachment, lever D in Fig. 2 being shown depressed and lever D" in normal position, all of the levers being mounted on a pivot rod a passing through the levers near one end and through the upturned ends of plates (Z of the attachment.

F is one of a series of valves actuated by a series of plungers B, the valve being guided by pins a, a and forced to close by spring Z). Swells G G, are provided, the latter swell being shown open and both being operated by suitable connections to a knee lever. The mutes are indicated by H H. The reeds and valves are contained in box L which, with the restof the operable parts, is mounted between two vertical end plates attached to the top of the wind chest by suitable fastenings to prevent displacement.

To stop E, mounted in the customary fashion on the stop boards E and E is attached the right angled connecting rod I bent at z to reach the crank arm 0 which is fulcrumed in the end plate K at 0 and is connected at c to a second arm 0 which, being bent upwardly, impinges on plate (Z, through the upturned ends of which the pivot rod a passes to support the front of pivot ends of the levers D and D. Thus when the stop is drawn out, as shown in full lines. the

ivoted ends of the levers D D will be raised into engagement with the buttons 0 and the connections controlling the extra set of reeds will be brought into position for use. Pressure on individual keys A will then be transmitted through the button C, lever D, and pin B to valve F. hen the stop is in, the pivot ends of the levers descend to a level with the dotted line below them and the lever 0 turns down as indicated by the quadrant and the dotted lines below it. It will thus be understood that with my attachment the capabilities of a five-octave organ may be extended to six octaves by using the attachment at one end, or to seven octaves by using an attachment at each end. I am aware that general ideas of this sort have entered into earlier constructions, and I am aware of the use of octave couplers, but the object of my invention is to provide a removable attachment which will insure reliable response to demands made on it, obviate the use of crossed levers, and extensive change in the construction of the instrument to which it is ap plied.

, Having thus described my invention, I claim i A removable attachment for a reed instrument having the usual keys and a wind chest furnished with an air hole, said attachment comprising a frame provided with an end plate, a box secured to the end plate and containing reeds, valves, mutes and swells, and resting directly on the top of the wind chest over said air hole, plungers, valves operable thereby, levers actuating the plungers, coupler buttons engaged by the under side of adjacent keys of the instrument, a connecting rod arranged to raise, sustain and lower one end of the plunger-operating 1evers, and a draw stop engaging said connecting rod, the whole being combined substantially as and for the purposes set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
